MaxiMet GMX501 Advanced Automatic Weather Station System

The GMX501 is engineered to ensure high measurement accuracy, low maintenance, and reliable continuous status reporting. This is a high-performance weather station is simple to install, use and maintain and provides 6 measured parameters. The GMX501 can also derive multiple additional parameters based on combining these measured parameters, such as gust, average wind speed and dew point providing more value as no additional sensors are needed for these additional parameters.

The GMX501 is engineered to ensure high measurement accuracy, low maintenance, and reliable continuous status reporting. It includes a range of sensor configurations allowing customers to select the model most appropriate to their needs.
Data output is downloaded as a single string which is available on a range of communications protocols SDI-12 is default, but can be switched by user to MODBUS, RS232, RS422, RS485 or NMEA (switch requires USB configuration cable).
